With the influence of economic globalization, the manufacturing mode of network operation has become a highly efficient means to improve the production efficiency of enterprises, and the internal collaboration between enterprises has become more and more important. Multimode operation and integrated optimization technology have become the main problem facing the development of manufacturing information technology, and is a development trend of manufacturing information construction. This paper establishes a multi-mode operation system and integration technology research based on wind turbine, which provides a certain technical basis and operation guarantee for the multi-mode organization and operation of wind turbine [1].
Information integration between heterogeneous systems through information integration bus is one
of the effective means to solve the integration of various information within and between enterprises
and realize the interconnection between different information. Through the information integration
bus to carry out information integration, the integration between various information systems is no
longer the original direct exchange of data integration, so that the whole integration processes
structure is simplified, and at the same time will effectively reduce the coupling degree of integration
between various information systems, so that the whole integration mode of intelligent manufacturing
becomes flexible, and the scalability and adaptability of integration performance is enhanced[
The standard conversion protocol of information defines the formatting scheme of standard information, which is mainly used to realize the uniform conversion of information between different application systems and different data formats, so as to achieve the purpose of consistent understanding of information between enterprises. It is actually a translator that converts the information output from the upper application system interface into a standard format for transmission, and then restores it according to the requirements of the destination application system.
In the standard conversion protocol of information, two models are mainly studied: the common information label model and the mapping model of information. The generic information label model is used for the unified expression of various exchanged information in networked collaborative design and manufacturing, and solves the problem of conversion between different data formats; the mapping model of information, on the other hand, carries out the corresponding conversion between information in standard formats and local application systems according to the generic information label model, and is used to solve the problem of conversion of information between different application systems. Through the cooperation of the above two models, the conversion and integration of information between different data formats and different application systems are realized. The process is shown in Fig1.

According to the heterogeneous system integration operation model proposed above, the external operation model for constructing an integrated bus of a wind turbine is shown in the following Figure 2.
The integration of enterprise information technology heterogeneous systems can be divided into information integration, functional integration, process integration and comprehensive integration, but fundamentally, it mainly includes information integration and functional integration. For information integration, the main idea is to synchronize the database changes of heterogeneous systems through the integration bus, so as to realize information integration based on database level; for functional integration, the main idea is to carry out unified interface conversion through the integration bus to realize the decoupling of interface changes of heterogeneous systems, and to carry out interface mapping and interface data conversion of heterogeneity. In order to realize the connection between information system and integration bus, an Agent (intelligent agent) is established as an intermediate layer between them. To facilitate the deployment of integration bus, the unified interface conversion module in integration bus, which is more coupled with information system, is put into Agent.
The design, manufacturing and O&M of a wind power company involve different systems, PLM system, ERP system and own developed O&M and big data analysis system respectively. The above systems use different platforms, different programming methods, different data expressions, etc. In order to reduce the integration coupling of the above systems, the integration bus is used for the initial integration between each system.For more details, see Figure 3.

ESB is a pre-assembled SOA implementation that contains the basic functional components
necessary to achieve the SOA hierarchical goals. ESB is the product of the combination of traditional
middleware technology and XML, Web services and other technologies to achieve accurate, efficient and
secure delivery of different messages and information for enterprise applications. Reusing existing
services and modules to meet changing business requirements.[
The SOA-based integrated environment for wind turbine design, manufacturing, operation and
maintenance is shown in Figure 4. The integration environment is divided into three parties based on
the SOA infrastructure: service demander, service provider and service intermediary. The three parties
correspond to the three roles in the classical SOA architecture, and at the same time, the basic
architecture of the platform matches each other and follows the SOA standard protocol. The manufacturing
middle party is composed of three layers: the representation layer uses JSP technology to realize
demand interaction with other actors; the service integration layer is the core integration layer, which
uses the enterprise service bus ESB to realize multi-protocol connection, conversion and management
functions. The platform selects synapse ESB tool as a service intermediary to complete the joint
execution, proxy, caching, load balancing and other services that may be generated in the dynamic
alliance of cloud manufacturing.[
In order to meet the heterogeneous resource information sharing needs of a wind power enterprise networked manufacturing, this paper establishes a service platform model based on multi-mode operation, proposes an optimization integration method for networked manufacturing, and applies it in the design and implementation of the prototype system of a wind power enterprise networked collaborative manufacturing service platform. In the future, the main consideration is to expand the scope of use in the wind power industry and further improve the integration and optimization methods of resource information ontology to meet the requirements of efficient and high-level cooperation in the industry. We will establish a pilot demonstration for the networked collaborative product development, lead the industry's technological development and paradigm shift, and promote the overall transformation and upgrading of the wind power industry. 4.
